There are several ways to find the DOIs in bulk:

Using Crossref's Simple Text Query

  • Make sure that your bibliography is formatted correctly in any citation style (e.g. APA or MLA)
  • List them in alphabetical order or presented as a numbered list.
  • Paste them in Crossref's Simple Text Query. The tool allows up to 1000 references per submission.

Using Zotero's DOI Manager Add-on

If you are already using Zotero to manage your references, you can use this add on to check for DOIs in just a few clicks.

  1. Download and install the add-on here. The installation instructions are on the Readme page.
  2. The add-on will now automatically check for DOIs every time you import or add new references.
  3. Alternatively, you can also right-click on the reference entry >> Manage DOIs >> Get Long DOIs or Verify and Clean DOIs


  • The add-on may not always find the DOI for every article. For such cases, the entry will be tagged under No DOI found so that you can manually search for them later in Crossref.
  • Be sure to double check the DOI found to ensure that it corresponds to the correct article.
